Sorry, I just didn’t include the full expression of the objective to try to minimize the code. I have fixed the order of the `@variable` statements. I have another thread where I have posted my updated code with a new problem [help-creating-a-jump-variable-array](https://discourse.julialang.org/t/help-creating-a-jump-variable-array/11515/5) So I won’t repost it here to reduce redundancy, however I can eventually post my full minimization expression if my problems aren’t worked out my other post. Thank you for your help!
